These older gen Quadlock phone cases are pretty rubbish for the price, but on sale, still probably cheaper/similar price to a cheap case and quadlock stick on pad to mount to a QL mount. Only bought to mount my old phone to MTB mount, don't want to risk new phone if I come off the bike.
What's rubbish about it? You can feel the mould seem all around the case, buttons are barely discernible to the bare hand, so imagine how hard it's to use buttons with gloves while riding. Fit is great however, and newer case architecture is a vast improvement on these older ones.
